Amlodipine

Amlodipine is a drug that is used for treating high blood pressure, certain types of angina, and coronary heart failure. The drug works by slowing down the rate at which calcium moves to your heart and blood vessel walls, allowing better blood flow. Amlodipine comes in the form of a tablet that is taken by mouth, usually once a day. Some possible side effects of this drug include dizziness, nausea, and headache.

How Does It Work?

Amlodipine is part of a class of drugs called calcium channel blockers. The drug helps slow down the rate at which calcium moves into your heart and into the blood vessel walls. This, in turn, helps to relax the vessels, which allows better blood flow and causes lower blood pressure. It also makes it easier for the heart to pump blood.

There are two basic types of calcium channel blockers: dihydropyridine and non-dihydropyridine. The most important difference between the two types is that non-dihydropyridine calcium channel blockers can slow the heart rate, while dihydropyridine calcium channel blockers do not. Amlodipine is a dihydropyridine calcium channel blocker, which means that it does not have an effect on the heart rate.
